7.2.2 Slack rope protection connections
Only if by-bass function is needed for Slack rope-function.
A “normally open” contact should be connected to either one of the multi-functional inputs.
The slack:
MFI1 or MFI2 Active load limit rope by-pass function operates according to the following logic
ON Slack rope by-pass function active (lowering allowed)
OFF Slack rope function active (lowering prevented when the load is below the set limit)
7.3 Intermediate load limits
In addition to the normal overload protection function, one, two or three intermediate load limits can be
selected. An intermediate load limit will prevent the hoisting motion when the measured load exceeds the
pre-set limit. The intermediate load limit operation is selected by assigning this function to one or both
multi-functional inputs.
